I claim: 1. A splitter box for recovering value-rich tailings from the discharge end of a spiral concentrator including vertical concentrate collection means comprising (a) central gravity conduit means located centrally or near the inside curve of the discharge end of the spiral for disposing of relatively value-poor tailings, and inner and outer conduit means on both the …
In a spiral separator of the kind used for the wet gravity separation of solids (Figs. 5 & 6) there are provided splitters (70,71,72) in vertically aligned troughs (20,21,22) which are operatively connected by a linkage (80) permitting adjustment of splitters in unison. Preferably the splitters are at corresponding locations of separate troughs and are in vertical register.

In lieu of tailings thickeners, a reclamation scheme to recover water in the tailings area is sometimes provided. Most times these systems tend to be relatively straightforward and it is obvious that the reclamation of a substantial quantity of water in close proximity to the concentrator can have decided economic benefits.
Jan 01, 2016· Spiral concentrators are robust gravity separation devices that allow the concentration of slurry streams in terms of a desired mineral of interest. The optimal splitter position in a spiral concentrator is dependent on the interface position(s) between concentrate, middlings and/or gangue streams in the spiral trough.
